Assertion while recording `ret == -ENOENT || ret == -ENODEV || ret == -ENOTBLK || ret == -EINVAL' failed to hold. unknown quotactl(0x5805)

Me again unfortunately with another smbd issue. Recording fails with this assertion failure (using latest git 1022e348 ):

[FATAL /home/aaptel/prog/rr/rr.git/src/record_syscall.cc:5009:rec_process_syscall_arch() errno: SUCCESS] 
 (task 28255 (rec:28255) at time 61003)
 -> Assertion `ret == -ENOENT || ret == -ENODEV || ret == -ENOTBLK || ret == -EINVAL' failed to hold.  unknown quotactl(0x5805)
Launch gdb with
  gdb '-l' '10000' '-ex' 'target extended-remote :28255' /tmp/smb/sbin/smbd

Steps to reproduce:

git clone git://git.samba.org/samba.git samba
cd samba
./buildtools/bin/waf configure -C -j8 \
                                    --disable-cups --enable-selftest --with-libarchive  \
                                    --enable-debug --picky-developer \
                                    --enable-developer \
                                    --bundled-libraries=ALL \
                                    --prefix=/tmp/smb/ \
                                    --localstatedir=/tmp/smbstate
./buildtools/bin/waf build -j8
./buildtools/bin/waf install
rm -rf /tmp/share
mkdir -p /tmp/share
chmod 777 /tmp/share
cat <<EOF > /tmp/smb/etc/smb.conf
[global]
logging = ringbuf
log level = 0
 
[share]
path = /tmp/share
read only = no
guest ok = yes
EOF
for i in $(seq 100 9000); do
    echo ABC${i}DEF > /tmp/share/${i}xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
done

as root:

rr record /tmp/smb/sbin/smbd -i

in other shell:

/tmp/smb/bin/smbclient //localhost/share -U% -c ls

Start in src/record_syscall.cc at the assertion near line 5009 and inspect how the recorder handles the unknown quotactl(0x5805) result. Reproduce with the provided Samba setup and rr record command; done means the recording no longer aborts on this syscall and the relevant behavior is covered by the project's existing validation.
